+ * src/SDCCsymt.h,
+ * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
+ support for standard C idiom of memory mapped variables; for
+ example, *((xdata int*)0x1234) = 1 is now internally equivalent
+ to xdata int at 0x1234 tempvar = 1.
+ * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
+ provided by Akiya ISHIDA

+ DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
+ refer to the const or volatile state of the pointer itself.

+ A few small changes that speed up the peephole optimizer.
+
+ * src/SDCCpeeph.c
+
+2003-08-22 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Try to make the peephole optimizer smarter by maintaining
+ an association between the assembly source code and the
+ iCodes that originated them. Put this information to use
+ with a new peephole rule condition "notVolatile" so that
+ the rules can be aggressive yet still safe.

+
+ * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

+ if the left or right operand symbols have the accuse flag set.

+2003-08-20 Erik Petrich <epetrich@ivorytower.norman.ok.us>
+
+ Changed the type of the result of the ! (NOT) operator to char;
+ previously it returned the same type as the source. This allows
+ us to eliminate all the genFloatNot functions (all of its target
+ implementations were very buggy) since !float can use the same
+ code as !long now.

+ pic patch provided by Slade Rich <slade_rich@yahoo.com>
+ 1. Interrupt would not compile properly. Ensure PCLATH register is saved
+ during interrupts. Ensure WSAVE is located at a shared bank address.
+ 2. Fixed page selection in some places
+ 3. Fixed BTFSS/C to where necessary use registers directly and not simply
+ the registers name strings.
+ 4. Fixed "signed / unsigned compare" compiler warnings.
+ 5. The PIC port manages its own allocation of the general purpose
+ registers, but makes no attempt to reuse them. As a result when
+ compiling it soon runs out of general purpose registers. Some
+ additional code was added to the files pcode.c and device.c to walk
+ through the function call tree and rename the registers so that they
+ get reused.

Made bitfield a distinct type from bit so that bitfields
Rules 246.x, 247.x relate to bitfields, the others speed up
access to xdata mapped I/O devices.
- * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
